Abell 2151 Hercules Galaxy Cluster

Revision title: Closeup

The Hercules Cluster (Abell 2151) is an impressive cluster of about 200 galaxies, distant 500 million light-years in the constellation Hercules.
It is rich in spiral galaxies and shows many interacting groups, i.e. Arp 272 (NGC 6050, IC 1179, and a third one) and Arp 71 ("integral" NGC 6045 and companion on its left tip, just visible here) and Arp 122 (NGC6040 spiral left and companion).
The brightest member is the giant elliptical galaxy NGC 6041.
The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure.
It was described by Harlow Shapley in 1933 for the first time.

The Hercules Cluster is not as rich in galaxies, nor as centrally concentrated, as the Coma cluster. Clusters of this kind may be rich in spiral and irregular galaxies, and in Abell 2151 we see many interacting galaxy pairs and small groupings of galaxies. In both the dynamics of the cluster and its galaxy population, it may be possible to view Hercules as less evolved than Coma. Recent observations show that many Coma-like clusters seen at higher redshifts (and thus as they were several billion years ago) have galaxy populations much like we see today in the Hercules cluster, with numerous spiral and interacting galaxies. Some combination of interactions, mergers, and effects of intracluster gas may be driving this change with time.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
